Door handle and lock set



FIG. 1 is a front view of the door handle and lock set showing my new design;

FIG. 2 is a left side view thereof with the opposite side being a mirror image; and

FIG. 3 is a top view thereof.

The broken lines of FIG. 1 indicate the edge of the door and in FIG. 2 represent the door surface upon which the door handle and lock set are mounted; the broken lines do not form part of the claimed design. 

The ornamental design for a door handle and lock set, substantially as shown and described.
